Glanville, 40, told Howard Stern that when Cibrian left her for Rimes, who she considered to be less attractive than her, it was not a good feeling. "I don't think she's unattractive," she clarified, "[But] she's way thinner than I am. It's not a hot look."

"Why do you think he went with her? Do you think it was money?" Stern asked.

"No. Now I think he stays with her because of the money, but he told me he was cheating the entire marriage, she said. "I think it's just like extra p----. He just likes it." (Cibrian, 39, was caught having an affair with his Northern Lights costar Rimes, 30, in early 2009. Vanderpump Rules star Scheana Marie, 27, came forward shortly after confessing she too had a relationship with Cibrian while he was still married to Glanville.)

Glanville assumed that Cibrian, who married Rimes in April 2011, "must be" living off her money, because "he's not working right now" and "they just bought a really fancy mansion. But Glanville, who shares custody of their sons Mason, 9, and Jake, 5, added that she hopes the actor gets a job again. She explained, "If he makes more money, I get more child support."

The former model argues that she has to be outspoken on the show in order to defend herself against the veteran housewives. "Those women were horrible. They are just horrible," she said, using the "C word" to describe her costars, without sharing specific names.

And, she claims, her frenemies also get paid more than she does. Glanville said she was paid $18,000 for her first season on Housewives, but "they upgraded me to a full-time Housewife so then I got $136,000 this year."

Still, she said the other girls are making $250,000 a year. "I want what they're getting," Glanville complained. "I feel like I work hard."

Nevertheless, the Drinking and Tweeting: And Other Brandi Blunders author is grateful for being a part of the show. "It gives you a platform to do a book, and you're getting wine deals and you're getting appearance fees," Glanville explained. "People are just throwing money at you. They're going, 'Do you wanna go here for ten grand?'"
